This study offers a novel description of the sinonasal microbiome, through an unsupervised machine learning approach combining dimensionality reduction and clustering. We apply our method to the International Sinonasal Microbiome Study (ISMS) dataset of 410 sinus swab samples. We propose three main sinonasal “microbiotypes” or “states”: the first is Corynebacterium-dominated, the second is Staphylococcus-dominated, and the third dominated by the other core genera of the sinonasal microbiome (Streptococcus, Haemophilus, Moraxella, and Pseudomonas). The prevalence of the three microbiotypes studied did not differ between healthy and diseased sinuses, but differences in their distribution were evident based …

Functional Characterisation Of Cancer-Associated Fibroblasts From Nasopharyngeal Carcinoma, Wee Lin Wong

Student Works (2020-2029)

Nasopharyngeal carcinoma (NPC) remains a major health issue in Southern China and Southeast Asia where the disease is endemic. Whilst the cure rate for early stage NPC is high, patients often present with late stage diseases and have a 5-year survival rate of less than 50%. NPC patients often suffer from severe treatment side effects because of the location of the tumours that is in proximity to various important organs in the head and neck region. Therefore, alternative therapeutic approaches are needed to improve the treatment outcomes and reduce patient morbidity. Targeted therapies are not in routine use to treat …

Using The Clinical Frailty Scale To Predict The Length Of Stay In Otolaryngology Unit In Taiwan, Wei-Kang Tung, Hsiang-Chin Hung, Wei-Chen Tung

Faculty Publications

Frailty was a common syndrome in geriatric clinic and general internal medical wards. Some authors had identified the Clinical Frailty Scale (CFS) as a predictor of length of stay in the acute medicine unit. However, the role of the Clinical Frailty Scale in the length of stay in otolaryngology unit had not been well studied. The objective of this study was to find out the correlation of the CFS in elderly patients admitted to otolaryngology unit and their length of stay. A retrospective medical chart review of 203 elderly patients admitted to the otolaryngology ward from January, 2014 to December, …

Prevention Of Oral Mucositis In Cancer Patients, Patricia E. Biel

Evidence-Based Practice Project Reports

Oral mucositis [OM] is one of the most severe non-hematological problems related to cancer treatments and can impact quality of life. It is linked to poorer outcomes due to the associated weight loss, pain, dehydration, and risk of developing life-threatening infections. The purpose of this evidence-based practice project was to determine if OM is preventable with the use of an oral care protocol and zinc supplementation when compared to use of oral care protocols alone. The Johns Hopkins Nursing Evidence-Based Practice Model was used to guide project implementation in an outpatient oncology office. Recommendations were developed from an exhaustive review …

L-Serine Reduces Reactive Oxygen Species Yield In Cisplatin Treated Zebrafish Utricles, Satya A. Moolani, Elvin Irihamye, Jerry D. Monroe, Michael E. Smith

Posters-at-the-Capitol

Cisplatin is a chemotherapy compound effective against a variety of cancers. However, it can act as an ototoxin and cause hearing loss by promoting reactive oxygen species (ROS) production in auditory tissues. The antioxidant amino acid, L-serine has been hypothesized to lower levels of cisplatin-mediated ROS. In this project, we investigated whether L-serine can reduce cisplatin-mediated ROS production in auditory tissue and potentially act as an otoprotectant during cisplatin chemotherapy. We used a zebrafish utricular tissue culture system and fluorescent ROS indicator dye to spectrophotometrically measure if L-serine could decrease reactive oxygen species levels in cisplatin-treated tissues. We found that …

Multivariate Analysis To Identify Potential Biomarkers For Prognosis And Treatment Resistance In Head And Neck Cancer Patients, Christina Ann Wicker

Theses and Dissertations--Toxicology and Cancer Biology

It is estimated that nearly 50,000 individuals in the United States will be diagnosed with head and neck cancer in 2017 (American Cancer Society www.cancer.org). Ninety percent of oral cancers are head and neck squamous cell carcinoma (HNSCC). Major obstacles in the treatment of HNSCC are recurrence and treatment resistance, which contributes to increased mortality. Therefore, there is increased need to determine genetic alterations in HNSCC that may be ideal novel drug targets, and biomarkers to improve diagnostic and prognostic testing.

Cortactin Phosphorylation By Casein Kinase 2 Regulates Actin Related Protein 2/3 Complex Activity And Invadopodia Function, Steven Michael Markwell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Malregulation of the actin cytoskeleton enhances tumor cell motility and invasion. The actin-binding protein cortactin facilitates branched actin network formation through activation of the actin-related protein (Arp) 2/3 complex. Arp2/3 complex activation is responsible for driving increased migration and extracellular matrix (ECM) degradation by governing invadopodia formation and activity. While cortactin-mediated activation of Arp2/3 complex and invadopodia regulation has been well established, signaling pathways responsible for governing cortactin binding to Arp2/3 are unknown. In this dissertation we identify casein kinase (CK) 2α phosphorylation of cortactin as a negative regulator of Arp2/3 binding. CK2α directly phosphorylates cortactin at a conserved threonine …

Department of Surgery Docs

Introduction: Oral squamous cell carcinoma (OSCC) the sixth leading cancer worldwide ranks as the most common cancer in males, and the third most common in females in Pakistan. It is influenced by risk factors which are widely consumed in our population. The epidermal growth factor receptor (EGFR) is a tyrosine kinase receptor that is imperative for cell signalling, growth and differentiation. It is mutated and overexpressed in a variety of cancers, while in OSCC it has been linked to poor patient survival; premalignant to malignant transformation and recurrence. This study investigates the use of EGFR as a prognostic factor …

Mallampati Scoring And Its Relation To Obstructive Sleep Apnea, Austin Korczak

Honors Capstones

According to the American Sleep Apnea Association potentially 80% of moderate to severe cases of Obstructive Sleep Apnea (OSA) go undiagnosed with even optimistic estimates stating that at least 22 million Americans are afflicted by the disorder. These numbers are expected to continue to increase due to the rising rates of obesity in America. As a result, reliable criteria that can help physicians accurately predict the presence of an underlying sleep disorder, whose symptoms are masked during the day, is highly sought after. The objective of this research is to begin defining these criteria via a literature review of articles …

Chemogenetic Stimulation Of The Hypoglossal Neurons Improves Upper Airway Patency, Thomas Curado, Kenneth Fishbein, Huy Pho, Michael Brennick, Olga Dergacheva, David Mendelowitz, +Several Additional Authors

Pharmacology and Physiology Faculty Publications

Obstructive sleep apnea (OSA) is characterized by recurrent upper airway obstruction during sleep. OSA leads to high cardiovascular morbidity and mortality. The pathogenesis of OSA has been linked to a defect in neuromuscular control of the pharynx. There is no effective pharmacotherapy for OSA. The objective of this study was to determine whether upper airway patency can be improved using chemogenetic approach by deploying designer receptors exclusively activated by designer drug (DREADD) in the hypoglossal motorneurons. DREADD (rAAV5-hSyn-hM3(Gq)-mCherry) and control virus (rAAV5-hSyn-EGFP) were stereotactically administered to the hypoglossal nucleus of C57BL/6J mice. In 6–8 weeks genioglossus EMG and dynamic MRI …

Empty Nose Syndrome—What Do We Know?, Ethan Frank, Christopher Church Md

Loma Linda University Student Journal

Empty nose syndrome is a complication of nasal surgery wherein patients develop a persistent, debilitating sense of nasal obstruction and dyspnea despite clear nasal cavities. It is characterized by a discrepancy between prominent subjective symptoms and near total lack of objective findings, making it difficult to diagnose. The pathophysiology of empty nose syndrome is a complex mix of aerodynamic, physiologic, and neurological changes leading to altered airflow and diminished sensory function. Evolving treatment options consist of medical symptom control or surgical reconstruction.

Mumps Myocarditis: A Forgotten Disease?, Sheraz Hussain, Mohammad Faizan Zahid, Arshalooz J. Rahman, Mehnaz A. Atiq, S. H. Ibrahim

Department of Paediatrics and Child Health

Mumps is an acute viral illness that follows a self-limiting course but up to 10% of cases have a complicated course with the involvement of other organ systems. Myocarditis is reported as a complication but the incidence has greatly fallen ever since the development of the mumps vaccine. A child presented to our department with parotid swelling and fever. Persistent tachycardia with irregular pulse led to further cardiac work up which showed decreased ejection fraction and raised serum cardiac enzymes, indicating myocardial damage. With ionotropic agents and supportive care, there was complete normalization of ejection fraction and serum cardiac enzyme …

Evolution And Otitis Media: A Review, And A Model To Explain High Prevalence In Indigenous Populations, Mahmood F. Bhutta

Human Biology Open Access Pre-Prints

Inflammation of the middle ear (otitis media) comprises a group of disorders that are highly prevalent in childhood, and indeed are amongst the most common disorders of childhood. Otitis media is also heritable, and has effects on fecundity. This means that otitis media is subject to evolution, yet the evolutionary selection forces that may determine susceptibility to otitis media have never been adequately explored.

Here I undertake a critical analysis of evolutionary forces that may determine susceptibility to middle ear inflammation. These forces include those determining function of the middle ear, those affecting host immunity, and those affecting colonization by, …
